Clip on calliper

Ever wanted a accurate way to measure things. Well now you do. This clip on calliper slides effortlessly along rulers (some rulers may not work for size differences. rulers that will work will be linked).. You can use glue to hold the cap in place if you like the product. Please leave makes, likes, comments, ratings, and constructive criticism to help make this a better print for you. I have included the files for you to make it more accessible for all users so please remix.
